A COMPARATIVE STUDY FOR SELECTION OF EFFECTIVE ELECTROLYTE SOLUTION FOR ELECTROCHEMICAL DISCHARGE MACHINING

Electrochemical discharge machining ECDM is an advanced hybrid machining process which can be successfully used for machining electrically non-conductive materials such as glass ceramics and composites materials which are now a day’s used extensively for engineering applications. It is combination of ECM and EDM. The performance of the process is highly non- linear and complex depends upon number of parameter s associated with physical and chemical partners of the process. However the performance largely depends on type and concentration of electrolyte solution used. The electrolyte also gov erns the wear of electrode and MRR of the process. This paper highlights on such facts associated with the electrolyte used and its impact on the process of ECDM.
